Main intrinsic and extrinsic apoptosis pathway gene expression ratio in the HT-29, Caco-2, cancer cells and KDR/293 normal cells that treated with indicated concentrations of dried materials from the methanolic extract secretion metabolites of bifidobacteria and with 5-FU as positive control group for 48 h. Target genes were normalized to GAPDH as housekeeping control gene. All experiments were performed in triplicate (n = 3) and statistic significances were accepted at P ≤ 0.05. ^*P ≤ 0.05, ^**P ≤ 0.01, as compared to control
